Enhancing organizational performance through strategy, innovation and leadership: The case of a F&V producer organization
No full textThis article is directed to examining the organizational experience of a producer organization (PO) of fruit & vegetables from organic farming in Sicily, looking closely at successful factors which helped to meet more creatively and effectively to the problems and opportunities it faced. Methods. The methodological approach is based on the Strategic Orientation Round (SOR) analysis, which is based on SWOT method to prioritize the alternatives generated. With this method, it was possible to identify the problems and formulate strategic options in order to support the process of innovation. Results and discussion. The results of the case study reveal some possible strategies for the development and enhancement of the organizational and marketing perfomances
Eliciting stakeholder preferences on the potential benefit of diversified small-scale fishery activities
Full text linkThis paper examines stakeholders' preferences concerning diversification of small scale fishery activities, which has become a necessity for many small-scale fishermen in order to provide additional sources of income, as their income is often inadequate. It's looks at participatory modelling as a potential tool to enhance mutual understanding and legitimacy. Fisheries stakeholders and those with an indirect interest in diversification of their activities were invited to participate in the process of framing the management problem and to give input and evaluate the scientific models that are used to provide suggestions to decision makers. We followed a number of different strategies to investigate the role of participatory knowledge development. The study empirically integrates the traditional models of multicriteria decision aid approach with the deliberative mapping perspective. We conclude that participatory modelling has the potential to facilitate and structure the deliberative process within a dialogue between scientists and stakeholders about uncertainties and the quality of the knowledge base. It can also contribute to collective learning, increase legitimacy, and advance scientific understanding
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Concepts and methods for sustainability assessment: Insights from food security
No full textInternational audienceAccording to the concept of sustainable development, available natural resources are limited and disproportionately exploited. The growing depletion of these resources is leading to intergenerational disparities, as it systematically deprives future generations of a standard of living even remotely comparable to the current one. Sustainability is an integrative and dynamic concept, composed of issues that have often been described as crossroads of interests and social initiatives, both economic and environmental. Being such a complex and multidimensional phenomenon, sustainability is thus very difficult to explore through traditional measurement approaches. The objective of this study is to define the research questions that subtend the concept of sustainability. In particular, the complexity of sustainability measurement in food security contexts and the approaches used for incorporating its economic, environmental and social facets will be analyzed
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
